Abstract

A comparative economic evaluation of bucking deciduous trees: A Case study of Oriental beech ( Fagus orientalis ) stands in Northeastern Turkey Abstract: The optimum bucking method assists loggers to determine optimum bucking combinations that maximized total economic value of harvested trees. Several previous studies investigated performance of optimum bucking method on coniferous trees in Turkish forestry. In this study, economic gain of using optimum bucking method was evaluated in deciduous forest of Oriental beech ( Fagus orientalis ) trees in northeastern region of Turkey. Network 2000 program was used to run optimum bucking method in a sample application. The findings of sample bucking application in Giresun Forest Regional Directorate were deemed to represent the optimum bucking data in nearby regional directorates (Artvin and Trabzon).

落叶倒立树种的比较经济评价:以土耳其东北部东方山毛榉林为例

摘要:最佳屈曲方法可帮助采伐者确定最优的屈曲组合，使采伐树木的总经济价值最大化。先前的一些研究调查了土耳其林业针叶树最佳屈曲方法的性能。本研究对土耳其东北地区东方山毛榉(Fagus orientalis)树木落叶林中采用最佳屈曲方法的经济效益进行了评价。在一个实例应用中，利用network2000程序运行了最优屈曲法。在吉雷松森林区域局的抽样屈曲应用结果被认为代表了附近区域局(阿尔特文和特拉布宗)的最佳屈曲数据。在此基础上，对土耳其整个东北地区采用最优折弯法生产东方山毛榉的经济效益进行了估算。将研究结果与传统屈曲方法的结果进行比较，评价了优化屈曲方法的性能。结果表明，与主要依靠采伐人员经验的传统方法相比，采用Network 2000程序进行最佳扣压，可使采伐的落叶树木平均经济价值提高14.37%，但在统计学上不显著。在生产东方山毛榉(Fagus orientalis)原木中使用最佳抗压的总体经济贡献估计为2,686,182.93土耳其里拉(TL)。关键词:最优抗压，网络分析，东方山毛榉，土耳其Yaprakli agaclarin boylanmasinda karsilastirmali经济学家，土耳其Yaprakli agaclarin kuzeydogusundaki Dogu kayini (Fagus orientalis)， mescereleri ornegi Ozet:最优boylama yontemi, uretilen agaclarin toplam经济学家，最优boylama kombinasyonlarina karar vermek icin ormaniscerine yardim eder。Birkac onceki calismada Turk ormanciliginda igne yapraklilar uzerine最佳boylama yonteminin performansi incelenmistir。但是，从理论上讲，最优的boylama是在经济学上，kazanci Turkiye'nin kuzeydogu bolgesinde Dogu kayini (Fagus orientalis)， yaprakli或manlarinda degerlendiilmistir。网络2000年的节目或网络上的最佳boylama - youyoulama - the - bestbestbestbestbestbestbestbestbestbestbestbestbestbestbestbestbestbest.com。giressun Orman Bolge Mudurlugunde ornek boylama uygulamasinin bulgularini yakin Bolge mudurluklerinde de (arvin - trabzon)最佳boylama verisi temsil etmesi kabul edilmistir。[footnoter.com] [footnoter.com] [footnoter.com] [footnoter.com] [footnoter.com]Calismadan elde edilen sonnuclear geleneksel()的翻译结果:最佳的boylama yonteminin kapasitesi degerlendiilmistir。网络2000程序kullanilarak gerceklestirilen最优boylama uygulamasinsonuclariinsonuclariintecrubeline bagli olarak gerceklesen gelenekselonteme .核技术核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术，核技术等。[2] [j] .中国农业大学学报(自然科学版)[j] .中国农业大学学报。Anahtar Kelimeler: Optimum boylama, ag analizi, dogu kayini, Turkiye。收稿(Gelis): 2016年4月8日-修订(Duzeltme): 2016年7月9日-接受(Kabul): 2016年7月9日引用(Atif): Pak, M.， Gulci, N.， 2017。落叶倒立树种的比较经济评价:以土耳其东北部东方山毛榉林为例。伊斯坦布尔大学林业学院学报，67(1):72-79。DOI: 10.17099 / jffiu.52687
